Kansas Secretary of State Kris Kobach, who is also a Romney adviser, is working with Republicans in the state to remove President Obama from the ballot, claiming insufficient evidence about his birth certificate.

Kobach is part of the State Objections Board along with Attorney General Derek Schmidt and Lt. Gov. Jeff Colyer, all Republicans. The Topeka Capital-Journal reported that on Thursday the board agreed consider whether to take Obama off the ballot because they said they lacked sufficient evidence about his birth certificate.

“I don’t think it’s a frivolous objection,” Kobach said, according to the Capital-Journal. “I do think the factual record could be supplemented.”
